3 dni temu · To prove that the surface area of a sphere of radius \(r\) is \(4 \pi r^2 \), one straightforward method we can use is calculus. We first have to realize that for a curve parameterized by \(x(t)\) and \(y(t\)), the arc length is \[ S = \int_a^b \sqrt{ \left(\frac{dy}{dt}\right)^2 + \left( \frac{dx}{dt}\right)^2 } \, dt.

3 dni temu · Coordinate geometry's distance formula is d = √[(x2 - x1)2 + (y2 - y1)2]. It is used to calculate the distance between two points, a point and a line, and two lines. Find 2D distance calculator, solved questions, and practice problems at GeeksforGeeks.
6 dni temu · These formulas allow for the computation of the linear distance between any two points given their coordinates. Example Calculation. For two points \(P_1(3, 2)\) and \(P_2(7, 8)\) in a 2D space, the distance is calculated as: \[ D = \sqrt{(7 - 3)^2 + (8 - 2)^2} = \sqrt{4^2 + 6^2} = \sqrt{16 + 36} = \sqrt{52} \approx 7.211 \] Importance and ...
11 cze 2024 · To calculate the surface area of a sphere with radius r, we use the formula: Surface Area of Sphere = 4πr2. This formula shows that the surface area of a sphere is directly proportional to the square of its radius. For example, if the radius of a sphere is doubled, its surface area increases by a factor of four.
